The Vortex is a marriage of the best features of two rear screen technologies - optical and diffusion. A 0.5 mm Fresnel lens gathers the light from the projector and directs it at a right angle through the screen. As the light exits the screen on the audience side, a diffusion medium redistributes the light evenly in all directions - up, down, left, right and center.

The result is an extraordinary projected image with superior resolution and color contrast, an exceptionally wide viewing cone in both the horizontal and vertical axes, extraordinary center-to-corner brightness ratio, uniform brightness without hot spots
